Fig. 7000
Lightweight Flexible Coupling
The Fig. 7000 Lightweight Flexible Coupling is designed for
applications where system fexibility is desired.
The Fig. 7000 Coupling is approximately 30% lighter in weight
than the Fig. 7001 Coupling, and allows for working pressure
ratings up to 600 psi (41.4 bar).
The Figure 7000 Lightweight Flexible Coupling is intended for
use in several applications. See gasket Grade Index for gasket
recommendations.
See technical data section for design factors.
